Ancient tiny teeth reveal first mammals lived more like reptiles — ScienceDaily

Pioneering analysis of 200 million-year-old teeth belonging to the earliest mammals suggests they functioned like their cold-blooded counterparts — reptiles, leading less active but much longer lives.

The research, led by the University of Bristol, UK and University of Helsinki, Finland, published today in Nature Communications, is the first time palaeontologists have been able to study the physiologies of early fossil mammals directly, and turns on its head what was previously believed about our earliest ancestors.

Fossils of teeth, the size of a pinhead, from two of the earliest mammals, Morganucodon and Kuehneotherium, were scanned for the first time using powerful X-rays, shedding new light on the lifespan and evolution of these small mammals, which roamed the earth alongside early dinosaurs and were believed to be warm-blooded by many scientists. This allowed the team to study growth rings in their tooth sockets, deposited every year like tree rings, which

The Tiny Technology Helping Cannabinoid Balance By CBD Products Inc. Make A Big Splash

LA JOLLA, Calif., Oct. 9, 2020 /PRNewswire-PRWeb/ — Nanotechnology has long been understood to support many facets of medical science. Researchers and manufacturers are taking this proven technology and are now applying it to one of the fastest growing consumer markets in the world – CBD. And no one has been more active in bringing this tiny technology to CBD consumers than CBD Products Inc, with their new nano inspired brand Cannabinoid Balance.

Having seen that nanotechnology could have a profound effect on absorption rates in the body, the team at CBD Products Inc. turned to NanoZorb™ to help deliver the cannabinoids and terpenes in their Cannabinoid Balance products into the bloodstream quicker.

As with so many things in science, Nano Technology works by increasing the contact area and in turn increases the rate of absorption. By using NanoZorb™Technology in their Cannabinoid Balance products, Anthony Tribunella realized that he

Based on optical matter, new machines could be used to move and manipulate tiny particles — ScienceDaily

Researchers have developed a tiny new machine that converts laser light into work. These optically powered machines self-assemble and could be used for nanoscale manipulation of tiny cargo for applications such as nanofluidics and particle sorting.

“Our work addresses a long-standing goal in the nanoscience community to create self-assembling nanoscale machines that can perform work in conventional environments such as room temperature liquids,” said research team leader Norbert F. Scherer from the University of Chicago.

Scherer and colleagues describe the new nanomachines in Optica, The Optical Society’s (OSA) journal for high-impact research. The machines are based on a type of matter known as optical matter in which metal nanoparticles are held together by light rather than the chemical bonds that hold together the atoms that make up typical matter.

“Both the energy for assembling the machine and the power to make it work come from light,” said Scherer. “Once

What tiny surfing robots teach us about surface tension — ScienceDaily

Spend an afternoon by a creek in the woods, and you’re likely to notice water striders — long-legged insects that dimple the surface of the water as they skate across. Or, dip one side of a toothpick in dish detergent before placing it in a bowl of water, and impress your grade schooler as the toothpick gently starts to move itself across the surface.

Both situations illustrate the concepts of surface tension and propulsion velocity. At Michigan Technological University, mechanical engineer Hassan Masoud and PhD student Saeed Jafari Kang have applied the lessons of the water strider and the soapy toothpick to develop an understanding of chemical manipulation of surface tension.

Their vehicle? Tiny surfing robots.

“During the past few decades, there have been many efforts to fabricate miniature robots, especially swimming robots,” said Masoud, an assistant professor in the mechanical engineering-engineering mechanics department. “Much less work has been done

Something as simple as changing the font of a message or cropping an image can be all it takes to bypass Facebook’s defenses against hoaxes and lies.

A new analysis by the international advocacy group Avaaz shines light on why, despite the tech giant’s efforts to stamp out misinformation about the coronavirus pandemic and the U.S. election, it’s so hard to stop bad actors from spreading these falsehoods.

“We found them getting around Facebook’s policies by just tweaking the misinformation a little bit,

Tiny Projection Of Vermeer Painting Demonstrates New Nanoscale Technology

Johannes Vermeer’s “Girl With a Pearl Earring” is not a very large painting, but the replica recently created by researchers in China and the USA is even smaller. Scientists at Nanjing University, University of Maryland and the National Institute of Standards and Technology have fine-tuned an existing technology so that it not only filters through light of different colors using an array of nanoscale structures, but also projects light with different intensities. To show their new method in action, they used it to generate a projection of Vermeer’s painting, including all the detail of the shaded areas.

The mechanism they used involved a set of tiny titanium dioxide pillars mounted on a small glass plate. The pillars are only

Small Nuclear Reactor Pilot Program: NuScale Tiny Reactor Project

  • Two of 35 cities have opted out of a pilot nuclear plant program powered by NuScale.
  • NuScale’s tiny modular reactors will be manufactured at Idaho National Laboratory.
  • Time will tell if these two opt-outs hold larger meaning for NuScale’s ambitious plans.

    Small modular reactor startup NuScale had a setback this week when two cities pulled out of a planned 35-city pilot program of new nuclear plants. As the first small reactor to break through many regulatory landmarks, NuScale has been under a great deal of public scrutiny. Is this a bump in the road or something more? That’s a question of perspective.

    ☢️ You like nuclear. So do we. Let’s nerd out over nuclear together.

    Nuclear power plants in the U.S. from the current generation are aging out, reaching “end of life” and beyond for the kind of technology they include. China is continuing to add gigantic nuclear power plants
